Lexan mission envelopes are hand-made with .010 acrylic material. The envelopes are used to hold critical checklists and can be written on with permanent Staedtler markers. The marker ink can then be 100% erased using a small amount of alcohol. Unlike clear vinyl plastic, the Lexan material will not create a ghosting effect and can be used multiple times.

Each envelope comes with 4 velcro adhesive dots which you stick to the corners. The velcro dots will allow you to secure the envelopes to the desired location within your own data cover system.
